High-performance Python bindings for nng (nanomsg-next-gen)

nng

High-performance Python bindings for nng (nanomsg-next-gen), written in Cython.

Nanomsg-next-gen (NNG) is a high-performance messaging library written in C, which provides a simple and efficient API for building distributed applications. It supports various communication patterns, such as request-reply, publish-subscribe, and pipeline, and offers features like message framing, protocol handling, and transport abstraction.

Why yet another Python wrapper for NNG?

I am aware of two already existing Python wrappers for NNG.

I have started developing python-nng because after having tested ZeroMQ for a project, I wanted a library with similar concepts but with less user boilerplate. NNG seemed a good fit, but the existing Python wrappers didn't seem as mature as the Python bindings for ZeroMQ. I wanted complete docstrings and examples, benchmarks to inform decisions, and complete error handling in the codebase. In addition, during my experimentation I found out that async methods for ZeroMQ had a significant overhead, and that I could reduce it with a custom Selector using zmq_poll. NNG being callback-based for completions, I hoped for a better asyncio integration and less async overhead. To achieve this level of integration, Cython is needed, which the other wrappers didn't utilize.

On the use of AI

Much of the writing has been assisted by AI (Claude Sonnet 4.6), in particular the benchmark code and the unit tests. I have 12 years of Python experience, and more in C/C++. I have written another Cython-based library DearCyGui. Thus while AI has been a great help, I have extensively reviewed, extended, and modified the code and documentation, and I am confident that the code is of good quality. If you find any issue, please open an issue or a PR.
